MACHINE FOR ROLLING IRON.

Specification of Letters Patent No. 23,425, dated March 29, 1859".

To all 'whom 'it may concern: Y Y

. Be it known that I, HENRY B. COMER, of Temperanceville, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improved Machine for Rolling Iron; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Similar letters refer to similar parts.

The nature of my invention consists in a mechanical arrangement for rolling iron by causing the iron to be rolled to pass between a series of rolls and through guides, the grooves in the rolls and the form of the guides being adapted in form and size to the article desired.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the accompanying drawings, Figure l is a top View of the machine. Fig. 2 is an end view. Fig. 3 is a side view. Figs. 4 and 5 represent the interior of the guides. Fig. 6 is a cut or sectional view of the contracting and expanding pulley used for regulating the motion of the rolls.

(a) is the base of the machine, are the housings which are used for support-ing the rolls, (c) are the guides which are placed between the rolls in front of the grooves, and are arranged as represented in Figs. l and 3, (d) and (d1) are the rolls, (e) are the journals or axes of the rolls, (f) are the journal boxes of the rolls, (g) are the caps of the housings (b), (It) are upright supports for the shafts (l, 2, 3 and 4), (i) are the caps for the upright supports (7L) and are used for holding the shafts (l, 2, 3, and 4) in their places. The axes of shafts (1, 2, 3, and 4) have their bearings in the upright supports (71,). The shafts (l, 2, 3 and 4) are armed with balance or ly wheels (j) and pulleys and on one end of each shaft is placed a female coupling (la). These couplings and the male couplings (l) which are on the end of each roll are constructed and operated in the usual manner.

The pulleys (n) are arranged as represented in Fig. l and the power is conveyed from one to the other by means of belts, end less chains or`other suitable devices represented by the dotted red lines. The pulleys (n.) are made as represented in Fig. 6, they consistof hub (y), arms (s), rim (u) and an outer rim (0) which is made in segments. Each of these segments is furnished with three or more arms which pass through the rim (fu). These arms are furnished with a thread of a screw, and each arm has two nuts one of which is placed on the inside and the other on the outside of the rim (u). By means of this arrangelnent t-he pulley may be contracted or expanded by simply operating the nuts (t). By having the pulleys (u.) thus arranged any desired motion or speed may be given to the rolls without f any change of the belts, for when one pulley is contracted another is expanded.

(m) are wheels which are placed on the rolls for the purpose of giving to the upper and lower roll the same speed. The end (27) of the guide is placed next to the rolls having the oval grooves the other end (q) being opposite to the square grooves in,

the next pair of rolls.

The operation of my improvement is as follows: The iron heilig prepared in blooms, billets or piles it is properly heated and then fed into the rolls having the largest grooves. These rolls cause it to pass through the guides between the irst and second set of rolls and into the second set of rolls, and thus it passes from one set of rolls through guides to another set, and so on, until it is rolled out into the desired form and size. By gradually changing the form of the guides the iron will be turned in any desired position so as to meet the grooves in the next s-et of rolls, and by changing the form of the iron in one set of rolls into a different form in the next set it will be more speedily and completely drawn out into the desired size and form.

I wish it to be clearly understood that I do not claim the use of guides in general.

Having thus described the nature, conguide and Change the position of the iron as it passes from one set of rolls into another l0 set, as hereindescribed and set fort-l1.
